When a player takes fortune die 'open career advances', it says you can add a fortune die to one of the primary characteristics listed on his career sheet.
The question is, do they have to be from each, or can the character advance one of them twice?
For example, if a Pit Fighter has 2 fortune die advances and his primary characteristics are Strength and Toughness, can he take 2 Toughness fortune dice? Or does he have to take one of each?
